MSESD2CAN from MSKSEMI, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | Protected line 1 (TVS diode to common pin 3); working voltage 24V VRWM, 27V breakdown at 1mA, ±30kV IEC 61000-4-2 ESD. |
| 2 | I/O2 | passive | Protected line 2 (TVS diode to common pin 3); working voltage 24V VRWM, 27V breakdown at 1mA, ±30kV IEC 61000-4-2 ESD. |
| 3 | COMMON | passive | Common pin joining the two TVS diodes in the pin configuration diagram; the datasheet does not state a ground or supply role for it. |
